Pharrell Williams is said to be planning a lavish bash this weekend to finally publicly celebrate his wedding to model and designer Helen Lasichanh.

The Blurred Lines hitmaker, 40, who married his bride in a secret ceremony in France in August, is throwing the party to toast his nuptials alongside friends and family at The Kampong botanical garden in Coconut Grove, Miami.

Guests expected include Jay Z and Justin Timberlake, who are also said to be performing, Robin Thicke, David Guetta and Gwen Stefani.

According to the New York Post’s Page Six, the gathering will be held outside and guests have been told to wear ‘garden party attire’.

They have also been asked to provide their shoe size, with the likelihood being that they will be asked to wear protective slippers to prevent the garden being damaged.

A source told the publication: ‘Pharrell has worked with everyone. He just produced Miley Cyrus’ album, he has worked with Beyoncé, Madonna, Shakira, Daft Punk, Kanye West and Jennifer Lopez. Half the music business will be there.’
